Has everybody forgotten that you can run multiple users on a computer, and if you set the permissions on files properly the agent can't read them?

Agents are uses on a Unix-based computer that is capable of and indeed was designed for multi-user collaboration.

Why not go for the simple solution?

Do you think most people under the age of 30 remember you can share a single computer between multiple users? When there was a single "home computer" or "PC" in the home, you learned about users and different rights. Unless you were a user back in those days or you've tinkered with any admin work, you wouldn't know this in 2026.
